    Hi Guys,

    I'm trying to insert a single photo into a video for youtube.

    By putting a single image exactly in the middle of a video, it uses it as the thumbnail.

    Anyway,

    the videos i have a High Definition 1080p.

    Using Adobe Premiere takes over 3hrs to add this picture

    Is there anyway to just open the mp4 file, add a single pic (say for 5secs), then just resave the video? I dont want to compress it, or rencode it, so i do not get why it takes 3hrs to encode.

    If my video is 400mb -- i would just like the new videos to be 401mb (with the added pic).

    Any ideas of a quick way to do this?

    Thanks so much for reading my message Any replies are really helpful.

    Cheers.

  2. doesn't matter what you add the still to, you're still going to have to re-encode.

  3. The general technique is encode it to the same specs as the other video (incl. audio codec, sample rate, video specs, fps, codec, dimensions etc...) then append the pieces A+B+C, where B is the video of the still. You can use avisynth, audiodub(), and blankclip() to insert the silence, and ImageSource() to generate the video of the still. This is harder than it sounds, but I've done it before adding a video still to the beginning.

    If you split A+C on a keyframe you should be able to do this losslessly with avidemux without re-encoding (ie. you just re-encode "B", but leave A,C untouched). If you don't cut on a keyframe, you will have to re-encode the few frames around the cutsite GOP, but it's better than re-encoding the whole thing.

    poisondeathray -- thanks so much!!!!

    Your guide worked perfect

    I used avidemux to split the video into two -- then just used Premiere to encode a tiny 5sec screenshot vid -- and then just joined it all back together with avidemux again.

    You've saved me hours and hours!!

    Cheers
